A 19th-century firehouse and a seven-story 20th-century annex make up this hotel in the heart of Kendall Square. It feels like a giant B&B, and not just because of the generous breakfast: Patchwork quilts, bright paint on the walls, country-style furniture, and personalized service add to the artsy, quirky atmosphere. Units in the low-rise firehouse are closer to street noise and subway vibrations than rooms in the seven-story annex. Tip: On weekends, free street parking usually isn’t too hard to find (if you don’t mind walking a couple of blocks).
